memory: Align MemoryRegionSections fields
MemoryRegionSection includes an Int128 'size' field;
on some platforms the compiler causes an alignment of this to
a 128bit boundary, leaving 8 bytes of dead space.
This deadspace can be filled with junk.
Move the size field to the top avoiding unnecessary alignment.
